Function: setAssetOracles(address asset, address edgeFeed, address chainlinkFeed, uint256 stalenessThreshold, uint256 customDeviationThreshold)

This function sets the oracles for an asset.

Inputs

• asset

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: An asset to set the oracles of.

• edgeFeed

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: An Edge feed to set the Edge oracle of.

• chainlinkFeed

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A Chainlink feed to set the Chainlink oracle of.

• stalenessThreshold

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A threshold to set the staleness of.

• customDeviationThreshold

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A custom deviation threshold to set the deviation threshold of.

Branches and code coverage

Intended branches

• Try to get the price of the asset from the Edge oracle.

  Test coverage

• Try to get the price of the asset from the Chainlink oracle.

  Test coverage

• Check if the price is stale.

  Test coverage

• Calculate the deviation between the Edge and Chainlink prices.

  Test coverage

• Set the oracles for the asset.

  Test coverage

Negative behavior

• Revert if the caller is not an owner.

  Negative test

• Revert if the asset is not a zero address.

  Negative test

• Revert if the Edge feed is not a zero address.

  Negative test

• Revert if the Chainlink feed is not a zero address.

  Negative test

• Revert if the staleness threshold is zero.

  Negative test

• Revert if the custom deviation threshold is greater than the max deviation threshold.
